To all whomz't may concern:

Be it known that I, MICHAEL HARTNETT, a citizen of the United States, residing at Milton, in the county of" Northumberland and Stateof Pennsylvania, have invented certain new and useful Improvements in Railwayflies, of which the following is a specification. f L v. i

This invention relates `to railway ties and particularly to such ties constructedin part of wood and in part "ofmetal, wlierebythe rail supported thereon is insulated, and may therefore be used equally well on steam and electric roads and on roads where the automatic block signals are used.

lThe object of the invention is to provide such ties O f simple and economical construction which may be very easily maintained after being once erected and put in use and with this object inview, the invention con sists in the improved construction and arrangement of parts which will be hereinafter fully described andV afterward specifically pointed out in the appended claims. Y

In order that the construction and operation thereof may be readily comprehended, I have illustrated an approved embodiment of my invention in the accompanying drawings and will now proceed to fully and speci* ically describe thefsame, having reference to said drawings in which y Figure 1 is a view of my improved'tie in elevation in position to support a pair of rails which are shown in section, mounted thereon.

Fig. 2, is a top plan view of the structure shown in Fig. 1.

Fig. 3, is a sectional view of the same on a longitudinal, vertical plane cutting centrally through the tie and rails shown in Figs. 1 and 2.

Fig. 1f, is a sectional view on the transverse vertical plane indicated by the broken line 4 4 of Figs. 1, 2 and 3.

Fig. 5 is a view, in elevation of one of the two wooden blocks used in the construction of my tie.

Fig. 6, is a view, in end elevation,-of one of these blocks.

Like reference characters mark the same parts wherever they appear in a plurality of the figures of the drawings.

Referring specifically to the drawings, 7 indicates the metallic baseof the tie, of trough-like form, extending the whole length of the tie, being transversely corrugated in its lower. surface, as at 8, in order toprevent any slippingiof the tie longitudinally, and transversely of the. length oil the rails. The sidesof the trough are indicated at 9,

its ends at 10 and small tops extending only ashort distance `from the ends, at 11. i The sides 9 are cut away at 12,13, leaving the central portions, at 14,015 full height.

At 15, `16 are blocks of wood which are fitted in thetrough near `each end, the outer ends I`17 of these" blocks fitting under the tops 11, both ends 17 and 18 being reduced in" vertical dimensionfto 1the` depth of" the trough of the tie.

Between the inner ends of the blocks 15 and 16, a metal cap 18a is fitted, having side flanges 19 which engage over the upper edges of the trough. Y

A screw bolt 20. has its head Qliin a T slot in the bottom of the trough and passes l duced inner ends of the wooden blocks and i as the outer ends of the blocks are under the tops 11, said blocks are rmly held by the bolt 2O against displacement.

Rails 24, 25 are spiked upon the wooden blocks, either with or without the tie plate sometimes used, preferably with the tie plate, to keep the block dry so that it will not decay as fast as it would without the tie plate.

The wooden blocks act as cushions in the tie and allow for expansion and contraction, as ,well as allowing the current. on electric roads to travel undisturbed through the rail. The. amount of wood forone tie as described will be less than one-thirdof the wooden tie now in use. The wooden blocks can easily be removed by removing the steel cap from the body of the tie, and lifting a block out when to be removed. `Thelife of this tie will be from Fifteen to twenty-five years, the drier the climate the longer the life of the tie. The tie having a corrugated bottom it cannot slip or workout of line, and the cost of maintenance in labor will be as one man to the greater force required with the present wooden tie. The bolt holding the cap is very easily replaced in case it should break as its-head lits ina `T slot in the bottom of the tie, and can be slipped out and removed.

y up through the troughand the center of the A duced outer ends litting under the caps, and means for securing the Vinner endso both-V Y Having thus fully described my invention,

Vwhat I claim and desire to secure by Letters Y Patent of the United States 'isz-- il. A. railway tie comprising a trough-like metallicy body open at the' top eXcept for end caps, wooden blocks in thetroughhaving re-` the blocks comprising a'metal cap engaging over said inner ends and the upper edges of the sides voflthe trough,.ab'olt with its'he'ad l -1 attachedwtov the bottom of the trough and reduced outer ends fitting under the caps,

and means for securing the inner ends of the blocksV comprising ametal capfresting upon the inner ends of the blocks and the upper edges of the trough, and a bolt securing the cap to the bottom o1' the trough.

3. A railway tie comprising a metallicv VtrouOh havinOf a T O'roove in the central )ortion of its bottom, wooden blocks in the ends of the trough, a metallic'cap on the central portion of the trougl'i resting on the inner Yends of the blocks and having edge flanges engaging over the upper edges of the trough sides, a bolt having its head in the T slot and passing through the cap, and a nut on Vthe bolt above the-cap.

In testimony whereof I aiiix mv signature.
